Al, everyone I knew that ran the MaxSpeed no longer does.
That said, I too have limited under hood clearance. I've been running a custom height 4150 stop from #1 Stop since we have first competed in S/ST.
Last season I swapped my 4150 carb to BLP's "large bore" 4150 which uses the same body as the twin blade. Once again I called onto Gary at #1 Stop who again built me a custom height stop that I will be using this season.
